Gingivitis / Gum Disease in Dogs and Cats

Gingivitis (early-stage periodontal disease)

Inflammation of the gums caused by plaque and tartar buildup along the gumline — the earliest, reversible stage of periodontal disease. One of the most common health issues in both dogs and cats.

Symptoms

  • Red, swollen, or inflamed gums
  • Bleeding gums, especially when eating or chewing
  • Bad breath (halitosis)
  • Visible plaque or tartar on the teeth
  • Dull, unkempt coat in cats, since grooming becomes painful
  • Reduced appetite in more advanced cases

Causes

  • Buildup of plaque, a film of bacteria and food particles, along the gumline
  • Plaque combined with saliva and minerals hardens into tartar, further irritating the gums
  • Poor or inconsistent dental hygiene
  • More common in small and toy dog breeds and short-muzzled dogs
  • In cats, gum inflammation can sometimes progress to stomatitis, a more severe, whole-mouth condition

Treatments

  • Professional dental cleaning to remove plaque and tartar above and below the gumline
  • Regular at-home toothbrushing to help prevent recurrence
  • Dental chews, diets, or water additives as supportive care
  • Left untreated, gingivitis progresses into periodontitis, leading to bone loss, tooth loss, and links to kidney, liver, and heart issues
